Invasive Lionfish: The Next Grouper?

They're beautiful - and they're deadly. And they're here. Lionfish are infesting waters around Florida, and there might be one tasty way to stem the tide of this invasive species.

Lionfish were named for the beautiful mane of deadly stingers that surround their body. They were introduced in South Florida in the mid-1980's, and have since spread throughout the Caribbean, the Gulf of Mexico and the Atlantic Coast to New England. They're voracious eaters, outcompeting everything in their path.

But lionfish have one weakness: they're delicious. So marketers are looking to make it the next hot seafood item. Whole Foods has sold more than 35,000 pounds of the delicacy in the past year. David Ventura is the supermarket chain's regional seafood coordinator.

"They've been very, very passionate about it, they've been very curious. Some of them are very well informed - especially residents that live in Florida, they're aware of the invasive species in Florida," Venture said of the reaction to carrying lionfish. "I personally eat it in the form of a sushi, ceviche, fish taco, pan sautéed. So it's very, very versatile. It's mild, it tastes very similar to grouper. Most comments are very positive, quite frankly."

The lionfish, a longstanding showstopper in home aquariums, is a flourishing invasive species in U.S. Southeast and Caribbean coastal waters. This invasive species has the potential to harm reef ecosystems because it is a top predator that competes for food and space with overfished native stocks such as snapper and grouper. Scientists fear that lionfish will also kill off helpful species such as algae-eating parrotfish, allowing seaweed to overtake the reefs. In the U.S., the lionfish population is continuing to grow and increase its range. This is largely because lionfish have no known predators and reproduce all year long; a mature female releases roughly two million eggs a year.

Saturday is "Lionfish Awareness and Removal Day" in Florida. Lionfish are an invasive species off Florida's coasts. People in southwest Florida are studying the fish's impact and others are helping to keep the invasive species' population under control.

This Saturday is not only Lionfish Removal and Awareness Day, it’s also the kick off for Florida’s Lionfish Challenge—an incentive program to encourage people to remove the nonnative species. State wildlife officials are doing a bit of a revamp this year.

Florida’s fishing industry has dealt with its fair share of problems, with oil spills and grouper shortages. But as Matthew Seeger reports, an article from Florida Taxwatch exposes another problem- ecological damage caused by a hungry little troublemaker known as the lionfish.
